This paper reports a rare case of an extraovarian endocervical mucinous borderline tumor (MBT) arising from extensive pelvic endometriosis in a 35-year-old woman with dysmenorrhea and vague lower abdominal pain, using MRI with pathologic correlation after surgery. MRI showed an elongated tubular cystic lesion diagnosed as hematosalpinx, deep infiltrating endometriosis features including obliteration of the cul-de-sac, and two small cul-de-sac cystic lesions with mural nodules and peripheral nodular enhancement that raised concern for malignancy. Histopathology confirmed endocervical-type mucinous cells and a gradual transition from endometriosis epithelium to mucinous tumor cells in lesions involving the cul-de-sac and left fallopian tube. A key limitation is that the evidence is based on a single case, which constrains generalizability of the proposed imaging appearance. This paper is centrally about endometriosis— it describes an extraovarian endocervical mucinous borderline tumor arising from extensive pelvic endometriosis with MRI features and surgical-pathologic confirmation.

Abstract

We report MR imaging findings of a rare case of endocervical mucinous borderline tumor (MBT) involving the cul-de-sac and left fallopian tube arising from extensive pelvic endometriosis with pathologic correlation in a 35-year-old woman presented with vague pelvic pain. Endocervical MBT is a type of endometriosis-associated carcinoma. Imaging findings of endocervical MBT are unilocular or oligolocular cystic lesions with enhancing mural nodules, which are different from those of the more common intestinal type MBT.
